... taking them yet until my doctor sees that I no longer need the medicine. I am 5'5 and weight 225lb. Will joining a gym help me to lose weight and keep it off? A gym can be expensive. I do not want to pay too much. I do yoga at home and it helps with my back pain but does not burn off much weight yet. I have lost 6lbs in the past two months. Does anyone know another way I could lost weight while it is still winter?
